Hi Gilles and Dave, I will work with some of the examples given and hope to do better this time. The examples have threading on a solid shaft. If I make a model with a solid shaft that is threaded how will it be possible to "cut out" the center leaving maybe a 1/4" thick wall for example?
Best regards,

May be you could post pics or sketch of what your looking for.

Hey Mike,
Welcome to SCF, Charles told me you would be joining this forum to get some help.
I agree with Gilles, if you can post images or even a stripped down model we can help you better.

this one also by KitoRaup

I think I know what you want. If your solid threaded shaft has a face for an end cap, you can draw the inner circle on that face, then use the push-pull tool to make a hollow center all the way through. You will need to locate the center of the spirals. [Rather have your core circle centered on the top face of the cylinder before you make the thread offset.] Also if you draw your object centered on the axis or a guide line it will help.
Layout the concentric circles in plan(group a copy of these and keep at the base for reference).

Hi Solo, Nice to meet you. I tried downloading the plugin screw1_5.rb from the ruby library depot. It had a page but when I tried downloading it said unavailable. Did an internet search for the plugin and found a Google discussion where someone had the same result saying unavailable. What I did see in that discussion is that SU 7 cannot join faces under 1/16". I'm not sure about SU 8 but assume that it is a similar problem. My diameter was 2" and the V notch was .101" so that may have been part of the problem. I'll get to a sketch later as I'm trying to do my homework 1st on this problem but if that is/was part of my problem and I need to start large then scale down please confirm. Best regards, Mike

This link works for me.

I confirm.
Links to the plugin.

No need for registration or something. Pushing the download button should work.
Maybe you could drop a PM to Didier. -
I went to the link Massimo provided and it is the same as the one I went to but just to be sure tried it with the same result of "page not available" upon downloading. I tried another link for a ruby plug in from the same site, k tools 5.0 , that was mentioned in another thread with the same result. Any suggestions for the ruby library depot? Maybe I need to join the website or something. Best regards, Mike
OK, found a couple links from another thread and got it to download but it wasn't from the Ruby library. Will work on this a bit and get back. Best regards, Mike -
Hello Solo and everyone, Well I kept trying and trying until something happened. Not quite sure how to get the outside of the pipe section to fill in only between the V notches and this is one thousand percent not to any scale. Basically, the V notch will be around .101" wide X .101" deep and the spacing between notches will be .101". This piece of pipe with a spiral shaped notch will be in different diameters from 2" down to about 1" and maybe even a little less. Then I hope to be able to very subtly change the dimensions to get exactly what is needed in each size. Please forgive the fact that I'm catching on to this whole thing not only slower than a 5th grader or 12 year old but now wondering if a 2nd grader would be leaving me in the dust on this learning curve. Thanks!
Best Regards,
Mike

Is this what you want?

Or something like this.

Artistic ?

How about the one in this picture
?This could go on all night with this gang!

Hello, I posted the tube with the v notch spiral but it only has an inside surface to the tube. When making an outside surface it covers what is supposed to be open on the notch portion. Is there a way to "fill in" the portions of the outside tube and not interfere with the notch?
I paid the premium membership in hopes to get some help. Internet is deathly slow here where I'm at so youtube is a slow process and not sure what keywords to use to find the solution to what I'm trying to do at this step. I'm guessing this is rediculously simple to you all but that is why I'm posting on the newbie forum.Best regards,

Oops, I did not see Peter's reply. Let me look into that one. Now I need to learn how he did it!

Hi Peter! Thanks! I tried using the shape bender plugin as the first effort before using the screw plugin. I could not get things to line up right and it would not do the spiral. I did get shape bender to work with simple letters, straight line, and curved line. There is a big time difference here. I'm in Afghanistan and we are 1/2 an hour from the rest of the world. I received the Makerbot Replicator 1st gen in the mail 2 days ago. It may be the only one in the country but that won't be the only 1st because I also probably built the only black-light ping pong table in the country complete with glow in the dark balls (I'm on a blackout FOB, Forward Operating Base). This is much appreciated. I left you a personal message stating some of the other "mod's" I'll need to do such as a version with cutouts and some tabs allowing it to be bolted with Makerbot made plastic bolts/nuts to the base. I'll need to make it in other sizes as well.
Question: Will I be able to scale it up or down and then make the V notches the same size by some type of modification? Had serious issues with the Makerbot as it came minus the power supply, right extruder not extruding, and warping. Wired my own Lambda 24vdc power supply, put a washer in the right extruder to get it working, and waiting on some pure Acetone so I can make better ABS slurry to get it to stick. I'm also going to buy the upgrade kit for the MK8 extruder with the spring/ball bearing. Going to make some good stuff once the files are complete. Please do not hesitate to send me an email at the address I messaged you and I can send you picture. Best regards, Mike -
Mike,
IDK on the status of Premium services. I think some of it is still in the process of being implemented. I'll post the SKP of the tube with the various steps. There are many steps that require techniques you may or may not have learned. So we'll see what you need advice on, but it's all native SU, except I think one "recurve" plugin-- but no spiral or bender tool.
The problem with the outside face is: this is created here by making a cylinder of the exact diameter, number of sides, and alignment to the edges of the outside spirals. One needs to take care keeping that geometry straight so that the spirals line up to the faces and vertical edges that make up the cylinder, and that they will "intersect" and split those faces. SKP is good at helping with this.
I'll post the SKP and maybe some other notes. First let me get a coffee...
Peter
